Description
Technical field
The invention belongs to technical field of polymer materials, it is material modified to relate to a kind of ABS, and it is material modified and preparation method thereof to relate in particular to a kind of high heat-resisting, high gloss, fire-retardant ABS.
Background technology
Acrylonitrile-butadiene-styrene copolymer (Acrylonitrile-butadine-styrene copolymer, ABS) because it has favorable rigidity, hardness, high tenacity and processing fluidity, and cost is low, in light weight, thereby is widely used in industries such as machinery, home electric, daily apparatus.Yet owing to contain divinyl rubber in the ABS material, oxygen index is about 18%, belongs to inflammable substance, if make household appliances, just need carry out flame-retardant modified to it.On the other hand, automotive industry and household electric appliances are also to the increase in demand of ABS material, all use the ABS material to produce as fascia, grid, electric water heater element, heating appliance shell (hair dryer etc.) etc., but the constructional feature of ABS material itself, be higher than be difficult to keep under 100 ℃ the situation its favorable rigidity, therefore need do the ABS material heat resistance modified.But the heat resistance modified and flame-retardant modified of ABS material fails to accomplish to carry out simultaneously at present.
In the market the flame-retardant modified of ABS mainly contained: tetrabromo-bisphenol, TDE, decabromodiphynly oxide, bromination epoxy etc.Wherein, the tetrabromo-bisphenol system be consumption the most widely, its major advantage is, can keep the performance of ABS resin and cheap preferably.But exist mobile too high, heatproof not, cause burning easily, background color is yellow and can not match colors white more saturating effect; The major advantage of TDE system is, do not need to add other auxiliary agents, only the suitable bed material of needs selection just can be made fire-retardant, heat-drawn wire at the product more than 90 ℃, but its shortcoming also clearly, and not shock-resistant, poor toughness, color are yellow, being limited in scope of use.The major advantage of decabromodiphynly oxide is cheap, but peculiar smell is too heavy in the combustion processes, cigarette is very big, because environmental issue is disabled.That bromination epoxy fire retardant does not need when using is composite with antimony, can well avoid limited because of containing arsenic environmental protection aspect in the antimony, and the decomposition temperature of brominated epoxy resin higher (more than 300 ℃), thereby the phenomenon of xanthochromia, imitation frosted glass can not appear, but its fusing point exceeds much than ABS resin, therefore in the big product process of injection moulding, because of the subregion does not have enough time to melt, easy sticking to mould tool.
ABS in the market is heat resistance modified to mainly contain: make alloy with material such as PC, add modes such as introducing heat-resisting monomer in heat-resistant agent modification, the polymerization process.In polymerization process, introduce heat-resisting monomer, comparatively complicated on implementation, and also limited to the lifting of ABS material thermal resistance; Make alloy material with polycarbonate, can do better controlled to mechanical property, thermotolerance by the change of PC content, but in the injection moulding process because mobile decline significantly and price are higher; Become alloy material with polymeric amide PA6 blending and modifying, then (0.45Mpa) HDT and Vicat softening temperature are higher under low load condition, aspect automotive upholstery, has very large consumption, but the PA/ABS alloy material belongs to dulling material, therefore appliance shell etc. require the surface of good effect aspect application very little, (1.82Mpa) HDT is still lower under the higher load condition.
High gloss ABS material in the market mainly contains: adopt the higher ABS raw material of acrylonitrile content, become the high gloss alloy material with material blending and modifyings such as PC, PMMA.Wherein, become the PMMA/ABS alloy, adopt suitable black masterbatch, can make the extraordinary ABS material of surface luster, and have good processing flowability, mechanical strength preferably with the PMMA blending and modifying.If but in prepared high gloss ABS material, add fire retardant, often make the surface of ABS material become misty mute light effect.This mainly is because fire retardant and ABS matrix resin can not be good compatible of molecule rank, just realized the phase-splitting on the homogeneous phase on the macroscopic view, the microcosmic, on the surface of failing to form " smooth " on the low-light on the material surface, cause light scatter, just misty mute light effect occurred.
Can learn that by above material modified can not the obtaining of ABS coordinated at present, limited the material modified use range of ABS between high heat resistance, surface of good gloss and flame retardant properties.
Summary of the invention
The technical problem to be solved in the present invention is, at the above-mentioned defective of prior art, provides a kind of and reaches high heat-resisting, high flame retardant simultaneously and have an ABS of high gloss material modified.
The technical problem that the present invention further will solve is to be, simple, easy to operate high heat-resisting, the high flame retardant of a kind of technology is provided and has the material modified preparation method of ABS of high gloss.
The technical solution adopted for the present invention to solve the technical problems is: a kind of high heat-resisting, high gloss, fire-retardant ABS are material modified, are made by the raw material of following parts by weight:
